Hello, If you look at most popular obbies they have an image that draws in a viewers attention (in this case the giant spongebob),
So for this reason I believe the 2nd one is better, however could be improved with a new, cartoony skybox instead of the photo realistic one you currently have, and possibly a new angle.
Alright. Thanks for the feedback! I changed the spongebob icon because, no offense, complete noobs were joining and they would rage quit after 1 minute.
I would recommend it to increase traffic to the game, maybe make it more eye catching. Obby game icons dont really have text on them, and if you was going to add it I would make sure its visible against the background.
